Just got these for $19.08 shipped off amazon and have to say I'll be buying a backup pair very soon. However, these IEM's are definitely amp/EQ-dependant. I can see how burn-in is definitely required if using them straight into an iPod, but going from my PC > D1 DAC > Marantz 2230 with boosted bass I'm completely satisfied with the current sound and I haven't even put 10 hours into them (these can sound even better?!)
Tested with various games with good sound design (Alan Wake, Braid, etc.)
Setup: PC (optical) > Audioengine D1 DAC > Marantz 2230 (+2 bass, 0 mid, 0 treble)
2 seperate tests:
Straight into DAC: Somewhat thin, unimpressive sound. Harsh highs.
DAC coupled with Marantz 2230: Deep, immersive bass. Non-fatiguing highs. No need for burn-in.
Straight in DAC: The gun sounds were weak and tinny. Had to lower volume b/c of the highs. Felt distanced from environment.
DAC coupled with 2230: Even the 9mm pistol sounded strong. Enveloping environmental sound effects such as wind and footsteps on dirt. Bass rattled these things during some cutscenes.
